FIELD OF THE INVENTION

The present disclosure relates to compositions and methods for enhancing the stability and survival of microbial spores in inoculant compositions.

BACKGROUND OF THE INVENTION

Inoculant compositions comprising agriculturally beneficial microorganisms are well known in the art. See, e.g., U.S. Pat. Nos. 5,484,464; 5,586,411; 5,695,541; 5,804,208; 5,916,029; 6,569,425; 6,808,917; 6,824,772; 7,429,477; 8,148,138; 8,278,247; 8,445,256; 8,883,679; 8,921,089; 8,999,698; 9,017,442; 9,101,088; 9,234,251; 9,340,464.

Because the effectiveness of such inoculant compositions generally depends on the ability of the microorganisms therein to survive and propagate following application, much effort has been made to increase the stability of agriculturally beneficial microorganisms in inoculant compositions. See, e.g., U.S. Pat. No. 8,011,132 (describing a method of adding trehalose, sucrose or glycerol to the substantially stationary phase of fermentation) and U.S. Pat. No. 9,090,884 (describing the microencapsulation of microorganisms in a water-soluble encapsulating material).

Nevertheless, there remains a need for improved compositions and methods for enhancing the stability and survival of microorganisms in inoculant compositions.

The abilities of the aforementioned inoculant compositions to disperse Penicillium bilaiae spores are tested by measuring the ease with which each inoculant composition can be mixed into 100 ml of water in a 250 ml Erlenmeyer flask at 130 rpm on an orbital shaker. As a follow up to this qualitative testing, the percentage of single spores (compared to clumps of >2 spores) in each inoculant composition is calculated by observing the spores under a microscope at 200× magnification. Each of the solid non-aqueous inoculant compositions of the present disclosure exhibits greater spore dispersion than the commercially available wettable powder.

Example 2 Stable Wettable Powders Enhance On-Seed Stability

Solid non-aqueous inoculant compositions of the present disclosure comprising spores of Penicillium bilaiae and a commercially available wettable powder comprising corresponding spores were coated on corn seeds treated with a commercially available pesticide.
